TO ALL WHOM IT MAY CONCERN:

Be it known that I, J. LITTLE HYDE, of the city, county, and State ofNew York, have invented a new and useful Improvement in RegulatorsforWa-tches; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawing, makin cation, which is a plan view of a regulatorconstructed according to my invention.

This invention consists in so constructing the index and scale of awatch regulator that the edge of the index shall form an angle with thelines of the scale, so that the said lines shall always be but partiallycovered by the index, whereby not only much less delicacy of sight andtouch is required'in making any desired adjustment of the index than hasbeen the case with regulators constructed in the ordinar the said indexmay also be adjusted with greater exactness.

To enable others to understand the nature and construction of myinvention, I will proceed-"to describe, with reference to the drawings,what I consider the best construction of my invention.

A represents the plate, and B the index or lever of the regulator. Thescale of the regulator is shown at b, and is engraved upon the surfaceof the plate A on the arc of a circle concentric with the axis of theindex or lever B. The long or pointed arm of the said index extends overthe scale in the usual or in any suitable manner. The graduated lineswhich mark the divisions of the scale 6, instead of being radial to theaxis'of the index or lever, as in those in common use, are tangential toa common circle concentric with the said axis of the index or lever, sothat the said graduated lines are drawn at an angle to the index orlever to whatever pointthe same is turned. In the drawing, the circle towhich the graduated lines of the scale are tangential is shown in redcolor. Inasmuch as the index or lever is situated at an angleto each ofthe graduated lines of the scale while crossing the same, as just hereinfully set forth, the said index cannot entirely cover the whole lengthof any one of the said lines, no matter in what position the lever mayhe placed, and consequently a portion of. each line over which it isrequired to move the lever in passing over it, so that much greaterfacility is afiorded for bringing the lever to any desired line thanwould be the case if the lines over which itis necessary to move thelever were entirely hidden underneath the same during such movementthereof and furthermore, by bringing the edge of the lever to anydesired point along the length of the proper line, the said lever may beadjusted with greater nicety and exactness than if it was required toadjust it between the radial liiies of an ordinary scale. The sameresult maybe accomplished with a scale having graduated lines radial to'thc axis of the index or lever by so bending or shaping the outer end ofthe said index that it will cross the said radial lines of the scalein'the same manner that the radial index crosses the tangential lines ofthescalc, when the regulator is constructed in the manner first hereindescribed.

What I claim as new, and desire to secure by Letters Patent, is-

So constructing the index and scale of the regulator that the edge ofthe index shall form such an angle with'the lines of the scale that oneof the said lines shall always be but partially covered by the index,substantiallyns herein described,for the purpose specified.
